Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71544, here are decompositions:

7 + 71537 = 71544
17 + 71527 = 71544
41 + 71503 = 71544
61 + 71483 = 71544
71 + 71473 = 71544
73 + 71471 = 71544
101 + 71443 = 71544
107 + 71437 = 71544

Showing the first eight; more decompositions exist.
